WELL-PUMP.

Specification of Letters Patent.

Patented Nov. 14., 1911.

' Application filed October 12, 1910. Serial No. 586,746.

To all whom it may concern:

Be it known that I,

JAMES P. .Nronoms,

well contractor, a citizen of the United States, residing at Weiner, in the county of Poinsett and State of Arkansas, have invented new and useful Improvements in VVell-Pumps, of which the following is a specification.

The primary object of the present invention is the provision of a pump for lifting water from great depths, although the invention may be readily adapted for Artesian or other wells for elevating water, oil or other elements.

The invention supplies will overcome the necessity casing in addition to the ordinary well tubing and which will separate the water from a pump which the working parts and at the same time in.- sure an ample supply .of lubricant to the several bearings and moving parts, thereby reducing the wear to a minimum and prolonging the period of service of .the pump and at the same time enabling the pump. to.

be operated by a minimum expenditureof power.

The pump embodies in its organization a series of lifting elements located at difierent levels, each of said elements consisting of a rotary lifter comprising inclined planes which operate by a screw action, the several parts being supported in a manner to equalize the load and prevent straining of the line of shaftin'gwhich would cause separation of the parts when the pump had been in service for a comparatively short length of time. a The invention consists of the novel fea tures, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claims. f

Referring to thedrawings, forming a part of the application, Figure l is a view in elevation of a pump embodying the invention. Fig. 2 is a vertical central section of the upper portion of the pump showing the parts on a larger scale. Fig. 3 is a vertical central section of the lower portion of the pump illustrating the parts on a larger scale. Fig. 4 is a horizontal section on the line m-a; of Fig. 3. Fig 5 is a top plan view of the pump.

Corresponding and like parts are referred. to in the following description, and indifor providing a provided at its upper cated in all the views of the drawings, by the same reference characters.

A pump tubing 1 lines the well and is end with a plate 18 which is secured to the timbers or framing at. the mouth of the well and upon which the pump head is mounted. is bolted or otherwise secured to the plate 18 and its horizontal member is of a size corresponding with the diameter of the pump tubing andis flanged to enable a line of piping to be bolted thereto. A frame 20 is secured to the upper end of the T-fitting 1 7 and comprises a base and uprights, the latter being connected at their upper ends by means of a cross-piece 22 in which is formed a central bearing to receive the upper end of the shaft. The bearing of the cross-piece 22 has a bushing or linings37 and is adapted to be lubricated by means of an oil 0 ening 36 extending through the side thereo The shaft comprises an upper ortion 3 and a main portion 2, the latter being formed in sections which are coupled in the manner presentl to be described. The upper portion 3 o the shaft is of larger diameter than the main portion 2 and is coupled to the latter by means of a sleeve 27 which is threaded to the adjacent ends of the parts 2 and 3 and further secured by means of pins.

pulley 35 is secured to the upper portion of the shaft section 3 and is prevented from downward displacement by means of a set collar 34. The pump portion at its lower end embodying an upper head 20 has a tubular extension 20" and a lower extension 20*, the latter forming a bearing for the lower portion of the shaft section 3 and having a bushing or lining 29. A shoulder is formed at the base of the upper part 20* of the tubular portion and supports a bearing plate 31. in the upper face of which is formed an annular groove constituting the lower part of'a ball race. A collar 32 is secured, by means of set screws 33, to the shaft section 3 and its lower end is outwardly flanged and formed in its lower face with an annular groove matching the annular .groove formed in the plate 81, and forming therewith a race to receive the balls 30. The n per portion 20 of the tubular part of t e pump head forms a guide and serves as a cup or receptacle to receive oil for lubricating the A T-fitting 17 tains an upward thrust :receiving a packing 14 25. A packing 28 is interposed between the upper end of the sleeve 24 and the lower end ofthe part 20 to insure a tight joint. The T-fitting 17 is flanged at its upper'andlower ends and the flanges have openings through which bolts 21 and 19 pass for connecting the fitting to the head 20 and plate 18.

Elevating devices 16 are located at intervals in the length of the shaft and well tubing and serve to lift the water or other liquid to be raised. Each of the water elevators comprises a hub portion and spiral flights or wings. The hubs of each of the elevating devices 16 are internally threaded and the ends of adjacent sections of the shaft 2 are screwed therein, thereby fixing the osition of the parts. Pins pass through the liubs of the elevating devices 16 and the threaded ends of the shaft sections screw therein to prevent any possible loosening of the joints. The elevating devices 16 operate by a rotary action to raise the water or other liquid to be lifted. A casing 4 incloses each of the elevating devices and is of a diameter 'tofit snugly within the well tubing 1. A

tubular portion a is connected by means of arms 6 with the lower end of each casing4 and forms a bearing for shaft 2 and means for coupling the pipe sections 6. The tubular portion a extends above and belowthe lower ends of the arms Z2 and is externally threaded at each of its ends. A packing 14 is located in the upper portion of the part a and. is retained in place by means of a nut 9. bushing or lining 13 1s fitted within the lower portion of the part and snugly fits the shaft 2. A bearin plate 12 is located within the lower end 0 the part a and susof the set collar 10 secured to the shaft 2 by means of set screws 11:: A coupling 7 is threaded upon the lower end of the part a and has the upper end of the pipe section'6 next below threaded thereto and the coupling 7 incloses the-set collar 10 and the joint formed between said set collar and the part a and part 12. The upper end of the. casing 4 has a head 5 bolted thereto, said head being similar in construction to the parts a and b. The head 5 consists of a tubular portion a and arms 6, the ends of the part a being threaded to receive parts 7 and 9 and also 7 and a bushing or lining 13. -A bearing plate 12 is fitted within the upper end of the part b and sustains the thrust of the set collar 10 which is secured by means of set screws 11 to the shaft 2. he pipe sections 6 are threaded into the v reduced ends cf the couplings 7. The shaft- 2 extends through the sections of the pipe 6 and through the casings 4 and the end bearing portions thereof. Lubricant fills the pipe sections 6 and is supplied to the moving parts as needed. The pipe sections are filled with oil prior to coupling the several through the horizontal sections together. The part 8 fitted to the lower end of the lowermost casing 4 is simishaft 2 may several sections being threaded to the elevating devices and the latter and the pipe 6 being lowered until the desired length of pipe and shaft is obtained. The pipe 6 and the several casings 4 are held stationary whereas the shaft 2 and the elevating devices 16 carried thereby are rotated, thereby causing the water or other liquid to be drawn upward into the well tubing and discharged member of the T- fitting 17. The linear strain upon the shaft 2 is relieved at each elevating device by means of the bearing plates 12 and the set collars 10, as will be readily understood from the foregoing taken in connection with the accompanying drawings.

The pump is comparatively simple in construction and effective in operation and cap'able of raising water from a great depth and it is not hecessary to employ the casing generally used for inclosing the well tubing as required by deep wells in general operation.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope hereto.

Having thus described the invention, what I claim as new is g 1. In a pump, the combination of a shaft, a rotary elevating device secured to the shaft, a casing encircling the rotary elevat-- ing device, tubular portions at opposite ends of said casing and having the shaft mounted therein, and packing at the inner ends of the tubular portions adjacent the rotary elevating device.

2. In a pump, the combination of a shaft, a rotary elevating device secured to the shaft, a casing encircling the rotary elevating device, tubular portions at opposite ends of said casing and having the shaft mounted of the claims appended v connected to therein, packing at the inner ends of the tubular portions adjacent the rotary elevating device, other packing at the outer ends of the tubular portions, bearing plates for confining the last mentioned packing, and set collars secured to the shaft and in contact with said bearing plates.

, 3. In a pump, the combination of a' shaft, rotary elevating devices secured at intervals to the shaft, casings encircling the rotary elevating devices, tubular portions connect-' ed by arms to the ends of the respective casings and forming and pipc'sections receiving the shaft and lar portions of the casing.

.vices, pipe sections bearings for the shaft,

the adjacent ends of the tubu-o devices secured tolthe shaft at intervals,

the several elevating deconnecting the casings and having the shaft passing therethrough,

casings encircling "and means for imparting rotary movement to the end of the shaft.

In testimony whereof I aflix my signature in presence of two Witnesses.
